UNITED sTATENT ormoni LAFAYETT BARTOO, OF EAST AURORA, NE'W YORK.

SASH-FASTENER.

Specification of Letters Patent No. 28,729, dated June 19, 1860.

To all whom it may concern.

Be it known that I, LAFAYETT BAR'roo, of East Aurora, Erie county, andState of New York, have invented a certain new and Improved IVindow Stopand Fastener; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the accompanying drawings, and the lettersof reference marked thereon, in which- Figure I is a front elevation ofmy improvement. Fig. II is a cross section of the same on line @-6.

Like letters refer to like parts in each of the figures.

A is the window casing. B, B', are the window sash.

C, O are spring stops which hold the lower sash in the frame and guideit when being raised or lowered. These stops fit in grooves made in thejambs (D) and have coiled springs (E) placed behind them which pressthem out from the grooves sufficiently to hold and guide the windowsash. The

ycross piece (e) at the top and the shoulders (6') in the sill at thebottom prevent them from being pressed out too far. By taking out thecross piece (e) the stops may be removed. The grooves in the jambs intowhich the stops fit are sufficiently deep to allow the stops to bepressed back entirely within them.

f is a catch projecting from stop (C) which catches into the series ofholes (g) in the side of the lower sash (B) and holds it at any desiredheight, it being disengaged b v pressing the stop inward until the catchf is withdrawn allowing the sash to be raised or lowered.

71, is a similar catch projecting from the stop (O) which catchesintothe series of holes (i) in the upper sash (B) and operating in thesame manner as the stop O and catch f.

From the foregoing description it will be seen that the spring stops C,C answer three distinct purposes: First, they answer the purpose of theordinary stop, that of holding the sash in place and guiding themovement thereof; second, they allow the sash to be removed at pleasurewithout removing the stops, it being simply necessary to press the stopsinto the grooves made in the j ambs to receive them thus leaving thesash free to be removed, (this will be found very convenient in removingthe window sash for cleaning;) third, they answer the purpose offasteners preventing the windows from being opened from the outside andfurnishing means to hold the window open at any desired height.

The spring stops O and C having the catches (f and it) for the combinedpurposes as specied.
